If you install a newer version of a package that is already on the system, configuration files that you have modified will remain intact.

If you uninstall a package, the package manager renames any configuration files you have modified from <file> to <file>.rpmsave. If you then re-install the package (probably to install a new version) the package manager creates a new <file> with
applicable defaults. You are responsible for applying any changes captured in the original configuration file to the new configuration file. In the case of Ubuntu and Debian upgrades, you will be
prompted if you have made changes to a file for which there is a new version; for details, see Automatic handling of configuration files by dpkg.

The upgrade is now complete.
